Migrants to ancient Rome, more advanced Mesolithic Swedish communities, delayed transatlantic flights, expanding bird populations, and greener deserts thanks to climate change. Here are five of the latest scientific studies published open-access this week.... Read more »

There’s something missing from all the coverage of Zika virus, the mosquito-spread flavivirus that’s spread across 26 countries in the Americas since May 2015. While Zika usually doesn’t cause symptoms in adults, the outbreak coincided with a 20- to 40-fold … Continue reading →... Read more »

I think that the day after Valentine’s Day is actually the best. After all, chocolate is 50 percent off. However, using the holiday as an excuse to delve into the myriad of studies that attempt to explain the complexity of human attraction and relationships is pretty fun. Last year I examined moves, specifically some fly dance moves and rather cheesy pick-up lines. Today, I think I’ll explore gift giving.In the field of animal behavior, gift giving (or nuptial gifts) is practically its own s........ Read more »

Humans, like all social animals, have a fundamental need for contact with others. This deeply ingrained instinct helps us to survive; it’s much easier to find food, shelter, and other necessities with a group than alone. Deprived of human contact, most people become lonely and emotionally distressed.

A new paper in PNAS raises the interesting suggestion that our brain function goes through yearly cycles. According to authors Christelle Meyer and colleagues, their findings reveal new evidence of seasonal effects in human cognitive brain function "that could contribute to cognitive changes at specific times of year."
However in my view, the study is too small to be conclusive.
Meyer et al. used fMRI to scan 28 young participants. Each of the volunteers spent 4 1/2 days in a laborator... Read more »

I won't keep you too long today as I bring the paper by Adam Young and colleagues  (open-access available here) to your attention and some discussions around the concept of inflammation and autism. To quote: "An emerging focus of research into the aetiology of ASC [autism spectrum condition] has suggested neuroinflammation as one candidate underlying [the] biological model."Including one Simon Baron-Cohen on the authorship list, I have to say that I was impressed to see this quite c........

Whatever the ins and outs behind the tragic shootings at Planned Parenthood clinic in Colorado, it seems safe to assume that the heated and inflammatory rhetoric that has characterised the debate around abortion in the USA has played a major role. A couple of weeks ago, Planned Parenthood innocently asked Twitter users for one word [Read More...]... Read more »

Scientists at the UCLA Eli and Edythe Broad Center of Regenerative Medicine and Stem Cell Research and Center for Duchenne Muscular Dystrophy at UCLA have developed a new approach that could eventually be used to treat Duchenne muscular dystrophy. The stem cell gene therapy could be applicable for 60 percent of people with Duchenne, which affects approximately 1 in 5,000 boys in the U.S. and is the most common fatal childhood genetic disease.

People are still talking about the Ebola virus and its deadly outbreak in West Africa, and now a new virus is making the headlines: mostly innocuous and fairly unknown until a few weeks ago, the Zika virus is suddenly dominating the news for its putative link with a congenital birth defect that causes babies to be born with abnormally small heads and undeveloped brains. But what is the Zika virus, and how can it be harmless to most people yet cause such harm to an unborn fetus? To answer this qu........ Read more »

Let's talk about hearts and how they get broken. Literally, with drugs. When we swallow a pill, it's often to help address a problem we're experiencing with a particular body part. An aching head or a sore throat, for example. The pill breaks down in our guts and we absorb the drug into our bloodstream. It travels around our body and eventually ends up at the hurting locale where it works to fix the problem. Unfortunately, sometimes the drug will end up somewhere else and act there to cause an u........ Read more »

Renal cell carcinomas (RCCs) can be life-threatening and although mostly sporadic, approximately 5% are associated with genetic conditions such as BHD. Early identification of families carrying cancer-predisposing mutations enables access to regular screening and earlier treatment. However, it can be difficult to distinguish between sporadic and inherited RCC based on standard immunohistological analysis. New research from Kato et al. (2016) assessed whether variability in the chromosomal status........ Read more »

I'll admit to being pretty fascinated by the Branched Chain α-Keto acid Dehydrogenase Kinase (BCKDK) gene. As per previous blog entries about this gene (see here and see here) and the important biological step it plays in the metabolism of the branched-chain amino acids (BCAAs), at least one 'form' of autism might be particularly sensitive to issues with it . I take it you've heard of the idea that the autisms (plural) might be a better description of autism? If you haven't, here is a p........ Read more »

Compared with Whites, Black Americans have high levels of an important stress hormone called cortisol circulating in their bloodstream. No-one really knows why this is, but the differences remain even after you take into account social and psychological factors. It seems likely that simply being black exposes you to a cumulative effect of increased lifetime [Read More...]... Read more »

Biosensors are powerful tools in synthetic biology for engineering metabolic pathways or controlling synthetic and native genetic circuits in bacteria. Scientists have had difficulty developing a method to engineer "designer" biosensor proteins that can precisely sense and report the presence of specific molecules, which has so far limited the number and variety of biosensor designs able to precisely regulate cell metabolism, cell biology, and synthetic gene circuits.

Scientists may be in agreement on the causes of climate change, but the US public is not.

A new agent of the tick-borne illness known as Lyme disease has emerged in the upper Midwest. The bacterium is genetically related to Borrelia burgdorferi, until now believed to be the only cause of Lyme disease in the United States. The name proposed for the bacterium is Borrelia mayonii because the work was conducted at the Mayo Clinic. B. mayonii has not been detected in patients outside of the Midwest (so far). The findings are described in The Lancet Infectious Disea........ Read more »

Home of tumbleweeds and roadrunners, it’s no surprise that the Southwest is the driest region of the United States.
